Abstract :
This work presents the design of an inductively source degenerated CMOS Differential Low Noise Amplifier (LNA) operating at 2 GHz. LNA is designed using UMC 0.18 μm technology and simulated in Cadence Spectre_RF tool to validate its performance. Power constrained methodology is used for the design of CMOS Differential Low Noise Amplifier. At 1.8V supply voltage, the designed LNA consumed 9mA current. The amplifier provides a power gain (S21) of 22.53dB, noise figure (NFmin) of 1.845dB, S11 of -9.781dB, S12 of -11.42dB and consumes 16.2mW of power.
